3 Claims.

This invention relates to looms and more particularly to picker checks for such devices.

One important object of the invention is to provide novel strap means and adjustments therefor to constitute picker checks.

A second important object of the invention is to provide novel means for adjusting the throw of such picker check straps.

A third important object of the invention is to provide novel spring means for controlling the resistance of the picker checks to the movement of the picker sticks in a forward direction.

With the above and other objects in view, as will be hereinafter apparent, the invention consists in general of certain novel details of construction and combination of parts hereinafter fully described, illustrated in the accompanying drawings and particularly pointed out in the appended claims.

In the accompanying drawings like characters of reference indicate like parts of the several views, and- Fig. l is a plan view of a portion of a loom showing one form of the invention applied thereto.

Fig. 2 is a front elevation thereof.

Fig. 3 is an end elevation thereof.

Fig. 4 is a side elevational View showing a second form of the invention.

Fig. 5 is a plan view of'the form shown in Fig. 4.

Fig. 6 is an end elevation of the form shown in Fig. 4.

Fig. 7 is a perspective view of the laterally slidable member.

Fig. 8 is a similar view of the L-shaped bracket.

In the form of the invention shown in Figs. 1, 2 and 3, there is provided a lay beam I0 having a slot II extending longitudinally thereof. The check device comprises a body or base member I2 which lies on top of the outer part of the beam I and is provided adjacent each end with a rearwardly opening slot I3. On top of each slot rests a washer I4 wherethrough extends a screw I which engages in the beam I0 and thus holds the base in spacial adjustment parallel to the slot II. Extending downwardly from the base I2 is a iiange I6 which serves to limit inward movement of the base I2. Extending upwardly from the rear part of the base adjacent one end thereof is a post I1 having a transversely arcuate front surface I8 and provided with a forwardly extending head I9. Projecting forwardly from the front edge of the base I2 is a lug having a forwardly opening slot 2| and l on their upper sides.

extending from the front of this slot to the 'inner or rear edge of the base I2 is a rectangular groove 22. On the base is mounted a laterally slidable member having a foot A23 provided with a tongue 24 fitting in the groove 22. A bolt 25 extends through the foot 23 and the'slot 2| and has on its lower end a nut 26. This bolt serves to clamp the foot 23 in adjusted position on the base I2. Extending upwardly from the foot 23 is a post 21 having its rear surface 28 arcuate in crosssection. Carried by the post 21 is a bracket 29 which extends toward the middle of the loom and has a widened end On the face of the widened end 30 is mounted aI split spring 3I, J-shaped in plan ywith the curved end 32 of the J adjacent the slot II. This spring 3l is secured to the end 30 by a bolt 33. Secured to the bracket 29 is an L-shaped guard member having a horizontal leg 34 secured to the top of the bracket 29 by a bolt 35. This guard member has a vertical leg 36 which depends down in spaced relation to the bracket 29. An endless strap 31 of leather or other flexible material having its peripheral wall vertical extends across the slot II to embrace the picker stick 38, the front side of the strap extends in front of the post I1, be.F hind the post 21 and in front offthe leg 35 while the rear part of the strap lies behind the picker stick 38. Thus, when the picker stick oscillates it hits alternately the end portions of the strap and tightens it, the portions alternately curved at the front part resisting slidingmovement of y the strap.

In the form of the invention shown in Figs.

4, 5 and 6 the picker stick is arranged to oscillate in a horizontal plane. is shown at 40 and is provided at its outer end with an angular extension 4I whereon is mounted an arm 42, the arm being provided with a slot 43 wherethrough a bolt 44 passes and is screwed into the extension 4I. The arm 42 has a pair of spaced rearwardly extending arms 45 rounded Also the arm 42 carries an upwardly extending arm 46 Whereto is secured an L-shaped bracket 41, a bolt 48 extending through a slot 49 to permit vertical adjustment of this bracket. The bracket 41 carries an arm 49 rounded on its lower side and projecting downwardly between the arms 45. The picker stick 50 lies between the lay 40 and the arm 42. The picker stick 50 is surrounded by a strap 5| which is sinuously disposed on one side between the arms 45 and 49. Also the arm 42 is provided with a head 52 which ts loosely in a bumper strap 53 supported by a head 54 which extends In this form the lay straps as to provide virtual shortening thereof.

What isclaimed and desired to be protected by Letters Patent is:

1. In a picker check, a lay having a picker guide, a picker oscillatable along said guide, a bracket secured to said lay at one side of said guide, a strap of elongated loop form having side portions on opposite sides of the slot and end portions crossing said slot adjacent opposite ends of the movement of the picker, said strap loosely surroundingl the picker, and means carried by said bracket and sinuously flexing vone side of the strap, `said means including anl adjustable element slidably mounted on the bracket to move lineally toward and. from .the picker guide for controlling the extent of iiexure of the exed side of the strap, adjustable spring means carried by the bracket and engageabler by the strap upon. the picker .approaching one end of its path of movement, and a single bolt passing through the bracket and securing said element and spring means in adjusted position.

2. In .a picker check, a lay having a picker guide slot, a picker oscillatable along said guide, a strap of elongated loop form surrounding said picker and having side portions on opposite sides of said slot, a bracket rigidly attached to said lay at one side of the slot and including an arm arranged at right angles to the lay, said bracket being provided with a pair of spaced strap flexing elements, a third flexing element guidingly and adjustably supported from one side of said arm, a picker check spring guided for adjustment on the other side of said arm, and means common to the third element and check spring for securing them in adjusted position on said arm.

3. In a picker check, a lay having a picker guide slot, a picker oscillatable along said guide, a strap of elongated loop form surrounding said picker and having side portions on opposite sides of said slot, a bracket rigidly attached to said lay at one side of the slot and including an arm arranged at right angles to the lay, said bracket being provided with a pair of spaced strap flexing elements, a third exing element guidingly and adjustably supported from one side of said arm, a picker check spring guided for adjustment on the other side of said arm, said spring being arranged for engagement by the strap upon movement of the picker in yone direction, and a bumper extending across .said slot for engagement by the strap at the other end of the travel of the picker.
